Title: Improvements in and relating to the synchronisation of television signals
Inventor: ANSTEY HAROLD GEORGE
IPC: H04N9/475
Filed: 1963-03-26
Abstract: 1,066,732. Television synchronization. BRITISH BROADCASTING CORPORATION. March 26, 1964 [March 26, 1963], No.11961/63. Heading H3A. In an arrangement for synchronizing pulse generators at remote television camera sites with a master synchronizing pulse generator at a central station, the pulse generator at a first remote site is synchronized with the master synchronizing pulse generator at the central station and provides signals for synchronizing the pulse generators at the further remote sites. The television signal at remote site 38 is applied via line 55 to a sync. separator 45 which supplies a synchronizing signal via lines 57, 58, 59 and 62 to one input of a phase error detector 35 at the central station. The master pulse generator supplies a second input to the detector which provides an error signal on line 63 to synchronize the pulse generator at site 38. The synchronizing signal output from separator 45 is also applied as one input to an error detector 41 at a second remote site which includes a source of television signals 39. The output from source 39 is applied to a sync separator 43 which supplies synchronizing pulses on line 65 to a second input to detector 41. The detector supplies an output error signal on line 67 to synchronize the signals from source 39. A similar arrangement is shown for synchronizing a source 40 at a further remote site. Where a television signal is required from source 38 switches 50 and 52 are thrown to the right, the video output from sync separator 45 is then recombined with the sync signal in adder 47, similarly separated and recombined in separator 46 and adder 61 and applied to separator 36 at the central station. The video output of the separator is then applied via a station selector switch 33 to an adder 37 where it is combined with sync signals from the master synchronizing pulse generator 34 before transmission. Television signals from sources 39 and 40 are obtained by suitably positioning switches 50 and 52.

Abstract: 352,570. Liquefying gases. FRANKL, M., 234, Ulmerstrasse, Augsburg, Germany. April 16, 1930, No. 12121. Convention date, April 19, 1929. Addition to 246,172, [Class 8 (ii), Air and gases, Treating &c.]. [Class 8 (ii).] Air &c. is compressed and the major portion is passed alternately through one or other of the cold accumulators a<1>, all to a rectifying column d the nitrogen &c. from which simultaneously flows out through the other accumulator. The remainder of the air passes through a coil s around which the oxygen withdrawn in gaseous form from the rectifier flows. The passage of the air and nitrogen through the accumulators is reversed periodically, say at three-minute intervals. The passage of air and oxygen through the exchanger f is continuous, but the valve y allows occasional reversal, so that the oxygen escaping through the coil s removes deposited rime. If the oxygen is to be obtained and stored under high pressure, it is withdrawn as liquid from the rectifier, and conveyed by a pump p to an alternative exchanger g in which it is vaporized in contact with the inflowing air. Specification 276,381, [Class 8 (ii), Air and gases, Treating &c.], is referred to.

Title: Improvements in the manufacture and the production of artificial threads, filaments and the like
IPC: D01F6/14
Filed: 1940-08-02
Abstract: 542,942. Artificial filaments. COURTAULDS, Ltd., and WILSON, D. L. Aug. 2, 1940, No. 12527. [Class 2 (ii)] Artificial filaments of polyvinyl alcohol are obtained by extruding an aqueous solution of water-soluble polyvinyl alcohol into a bath consisting of an organic liquid having an appreciable solvent power for water. The organic liquid may be a mixture of such liquids and it may contain water or other additions. Spinning solutions of various concentrations, viscosities, and temperatures may be used. The organic setting liquid may be acetone, ethyl lactate, or ethylenel glycol mono-ethyl ether. In order to prevent deterioration or sticking of the filaments during the subsequent drying operation owing to the presence of an increasing proportion of water, the filaments may be passed from the setting bath into another bath containing a liquid of different composition from the first. The second bath may consist of a solution of diethylene glycol mono-ethyl ether (hydroxyethoxy-ethyl ether), or ethylene chlorhydrin, and water. The filaments may be stretched, e.g. while passing through the second bath. The filaments obtained are weakened by cold water and dissolved by hot water. They may be rendered resistant to water by treating them with formaldehyde or with an acid chloride. Specification 542,943 is referred to.

Title: Improvements in repeaters for electric carrier wave signal pulses
IPC: H03K3/78
Filed: 1944-06-30
Abstract: 582,231. Pulse modulation; wireless signalling. STANDARD TELEPHONES & CABLES, Ltd. June 30, 1944, No. 12532. Convention date, July 1, 1943. [Class 40 (v)] A repeater for electric carrier wave signal pulses comprises a thermionic valve associated with a resonant circuit and with a blocking circuit for generating amplified pulses of highfrequency waves having a repetition rate close 'to that of the said signal pulses, and means for applying the said. signal pulses to the control grid of the valve for synchronizing the said amplified pulses, characterised by the provision of means for delaying the application of the said pulses to the control grid whereby each amplified pulse is generated later than the corresponding signal pulse. The Figure shows an arrangement suitable for relaying time modulated pulses of high-frequency energy. Valve 15 oscillates at a radio frequency determined by circuit LC to produce pulses in an antenna, not shown, coupled to inductance L at a repetition frequency determined by condenser 24 and resistance 25 in the grid circuit. The pulse period is made slightly longer than the longest interval between the incoming timemodulated pulses and so the oscillator locks in to the incoming pulses and radiates corresponding amplified time-modulated pulses. The width of the output pulse can be varied by altering the magnitude of condenser 24. Application of the incoming pulses to the grid 17 is delayed by the provision of an inductance 60 inserted in lead 21 between circuit LC and point 28, so that the repeated pulses are delayed for a selected interval of time. The device may be used for extending the useful range of a pulse modulation transmitter particularly over rough ground. Specification 509,820 is referred to.

Abstract: 758,564. Valves. GLASCOCK BROS. MANUFACTURING CO. May 1, 1954, No. 12718/54. Class 135. In a faucet for pre-mixed carbonated beverage the body has transversely intersecting conduits 225, 250, the inlet to one having a conical seat 27a and carrying a hollow barrel 22 connected to the liquid source at 23a, and a valve 27 with an extension 253 which just clears the inside of the barrel so that the liquid flows to the seat as a thin sheet. The clearance increases exponentially towards the seat, the angle of the seat is chosen to reverse the liquid flow and avoid cavitation, and a vane 29 in the outlet 28 prevents swirling so that loss of carbonation of the beverage is avoided. A resilient sleeve 26 on the valve-actuating rod 24 closes a vent 23 when the valve 27 is opened and reopens it when the valve is released for closing by the pressure of the liquid acting on the extension.

Abstract: 877,127. Gas turbines. NAPIER & SON Ltd., D. April 7, 1960 [April 15, 1959], No. 12855/59. Class 110 (3). In a gas turbine in which the rotor is in the form of a disc 23 and there is at least one passage 29 partly bounded by the rotor disc and through which a coolant is caused to flow, a temperature-sensing device is disposed in the said passage near the periphery of the rotor disc in a position where a flow of hot turbine gases in contact with the device will occur on interruption in the flow of coolant. The invention is shown applied in the case of a gas turbine engine in which the turbine 23, 24 is a separate power turbine and cooling fluid such as air tapped from the engine compressor is supplied to the space 29 between the downstream face of the rotor disc 23 and the casing wall 28 through a series of inlets 30, the cooling fluid finally discharging through the annular gap 31 into the exhaust duct 22. The temperature-sensing device is in the form of a thermocouple 34 contained in a tube 35, the junction 37 being disposed within a perforated thimble 38 and located within the space 29. The thimble 38 protects the junction 37 from direct radiation from the rotor disc while the perforations 39 permit coolant fluid to flow in contact with the junction. A rise in temperature in the space 29 due to failure of the coolant supply is sensed by the thermocouple which actuates either a warning device or a device to reduce or cut off the fuel supply to the combustion equipment.
